Define blank form for graphic workpiece simulation
Define tool in the program
Call tool in the spindle axis and with the spindle speed S
Retract tool in the spindle axis at rapid traverse FMAX
Pre-position the tool
Move to working depth at feed rate F = 1000 mm/min
Approach the contour at point 1
Tangential approach to circle with R=2 mm
Point 2: first straight line for corner 2
Insert radius with R = 10 mm, feed rate: 150 mm/min
Move to point 3: Starting point of the arc with CR
Move to point 4: End point of the arc with CR, radius 30 mm
Move to point 5
Move to point 6
Move to point 7: End point of the arc, radius with tangential
connection to point 6, TNC automatically calculates the radius
Move to last contour point 1
Tangential departure from circle with R=2 mm
Retract tool in the working plane
Retract tool in the spindle axis, end of program
